Abstract
Method and apparatus 40 for securing a cut sheet 14 bearing a repositionable pressure-sensitive adhesive 140 directly to an advertising signatures 12. A linerless elongated sheeting 54 having a backside 56 partially coated with a repositionable adhesive 140 is transported to a cutting mechanism 60 without having the adhesive 140 make substantial contact with the apparatus 40. The linerless elongated sheeting 54 is severed by the cutting mechanism 60 to provide a cut repositionable sheet 14 which is subsequently adhered to the advertising signature 12.
